<h2 id="dartio-包无法使用造成的影响">dart:io 包无法使用造成的影响</h2>
<p><code>dart:io</code>是一个在 flutter 中常用的包,但是在 web 版中是使用不了的</p>
<h3 id="dio-不能用">dio 不能用</h3>
<p><code>dio</code>包用不了,因为 dio 包是依托于 dart:io 包中的 HttpClient 进行的封装</p>
<p>并且因为国内很多初学者朋友人云亦云的选择了 dio 作为 http 的请求框架,所以今后如果有打算想要做 flutter_web 版的朋友可能现在就要考虑一下 dio 的使用问题了</p>
<p>当然 dio 包今后也可以迁移底层访问库为<a href="https://pub.dev/packages/http">http</a>,再进行二次封装形成 dio_with_http 那就是另一个故事了</p>
<p>另外 web 中的 http 请求可以使用 <a href="https://api.dartlang.org/stable/2.3.0/dart-html/HttpRequest-class.html">dart:html 中的 HttpRequest</a></p>
<p>使用<a href="https://pub.dev/packages/http">http</a>库的访问如下:</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-dart" data-lang="dart"><span style="color:#66d9ef">import</span> <span style="color:#e6db74">&#39;package:http/http.dart&#39;</span> <span style="color:#66d9ef">as</span> http;

<hr>
<p>在 flutter_web 浏览器中需要注意的一点是, 无论你使用什么访问框架来访问 http,都会遇到跨域的问题, 跨域问题是一个经典的web前端开发问题, 搜索引擎中的解决方案和完善的说明有很多, 请自行理解</p>
<h3 id="file-相关的-api-无法使用">File 相关的 api 无法使用</h3>
<p>在 flutter 移动版中,经常会遇到需要使用 File 来操作文件的情况,下载/读取文件都需要 File 的支持</p>
<h3 id="socketwebsocket">Socket/WebSocket</h3>
<p>前面说了 HttpClient 不能用,io 包中还包含 Socket/Websocket, 它们都是 dart:io 的类, 所以都无法使用</p>
<h2 id="darthtml-包的使用">dart:html 包的使用</h2>
<p>虽然不建议使用,但是这东西在 flutter_web 中是可用的</p>
<p>比如,我修改 web/index.html, 添加一个<code>h1</code>标签</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-html" data-lang="html"><span style="color:#75715e">&lt;!DOCTYPE html&gt;</span>

  }
</code></pre></div><p>这样就可以像传统的 js 一样操作 dom 元素, 然后将数字设置为当前的数字
